As always works very well, and lasts a long time. Keeps the algae at bay and the PO4 down to levels my SPS like.

Was experiencing Phosphate levels of .10 ppm set this up with the BRS dual reactor. After 24 hrs PO4 dropped to .05 ppm and after 48 hrs PO4 dropped to .01 ppm. Thanks BRS!

I had problems with phosphates and every product i used temporary lowered my levels for only a few days, and even then only had them down to 0.04. I decided to order this product along with the BRS reactor and i am not disappointed. I had this stuff in for about 1 week and on the 2nd day, i had 0 and i mean 0 phosphates!

I have used this GFO for a few months now and have had no issues other than the typical dust that comes with all gfo products. I just run 2 gallons of ro water through it and have no complaints!

Great product that does what it saysBy Ericon 5/7/2014

This stuff is great and absolutely reduced my phosphates. I've also used the high capacity. The bulk gfo does clump quite a bit and produces dust. I buy the high capacity now with no problems. Great stuff though.

Good Value...but needs frequent changingBy Danielon 5/3/2014

This media is a great value, the cost is well worth it for the performance it provides. The only reason I didn't give it a five was for the fact that it solidifies faster than the BRS High Capacity GFO when dosing 2-part.

I have no idea why I have not started to run this in my aquarium my corals started to open better after I started to run this in the BRS Dual Reactor. This stuff works great and it last a long time as well. Also I started to see some algae growth and after a week it started to disappear.

I've used pretty much all the major brands over the past several years, and I've got to say this is the best GFO in the industry. Thanks BRS for making a great product, and making it affordable to have a clear tank, also your small particle lignite carbon and is a great product as well.

I use it in a reactor and it performs as advertised.

GFO is king for phosphate removal. I run it in a reactor, and it works great!
